When Connie is trying to seduce Charlie, the back-scratcher she is holding changes orientation between shots.
In the living room, as Hoff begins "We all love you...", his hands are clasped in front of him. But on the cut, in mid-sentence ("...you're a great artist..."), his arms are spread wide.
After Charlie has his falling out with Hoff, he and Marion sit on the couch. Charlie has his arm over Marion's shoulder, but in the cut to a closer shot, Marion's hand is raised to hold Charlie's hand.
The camera and operator are visibly reflected in one scene in the living room.
